What's WeChat's strongest moat? It's not technology - it's human nature.

Even with all its limitations (blocked links, 500-person group limits), people stick with WeChat instead of moving to Telegram or Discord. Why? Simple - network effects and switching costs.

Once everyone's using an app, it creates this snowball effect of "well, I have to use it too!" Add to that all your contacts, daily habits, and chat history - who wants to start over?

Here's the real kicker - human laziness is actually WeChat's best defense. We'd rather deal with minor annoyances than go through the hassle of switching platforms and rebuilding our social circles.

Sometimes the strongest moat isn't built with technology, but with human behavior.
